Whats with my brakes?

[AERO]

I'll keep this as simple and quick as possible:

I have the stock brakes (PP brakes). I have been running RBF600 fluid for about 6 months, but those 6 months have included 6 track days.

Just recently I started to notice what I thought was just warped brake rotors, but I'm starting to wonder if thats not it anymore.

When I am gently slowing to a stop, I feel an inconsistency in my braking. Its not like a shake or vibration I would think warped rotors feel like. Its more like just an inconsistent brake performance. I feel no vibration at higher speeds, I only notice it at much lower speeds. It feels to me like a brake booster isn't running a consistent power.

Is it possible the fluid needs changing? Or a brake booster? Or is it most likely just a warped rotor? Could it be bubbles in the fluid? Fluid breakdown? Or did I just wreck my rotors at the track?

Thanks for any input!

Warped rotors get worse and worse at a pretty consistent, noticeable rate. If it gets worse it’s likely the rotors. If it remains difficult to pin down, it’s probably something with the braking system (fluid/master cyl/booster)

Does the steering wheel rock back and forth?

the 6 track days probably did heat up the fluid to the point where it's damaged. So, yes try flushing the brake fluid first

No. And I only really notice anything at low speeds

I'll do that first, thanks!

Bed the brakes again. Probably uneven pad compound deposits on the rotors. You can also take the rotors off sand them down (there’s methods on how to do this), reinstall and bed the brakes.

Thanks. Ill look into this. Its not something I've done before. The stock brakes do surprisingly well on the track. I've beaten them!

It's uneven deposits of pad material on the rotors from overheating the pads on track. You can remove them with steel wool.

Get RS3 brake deflectors and get a pad with a higher heat range.

Thanks man! I guess I should look into pads that can take higher heat.

And RS3 deflectors.

I think I'll just replace the pads. I seriously beat on them this summer. I did a lot of hard track days.

Are the RS3 deflectors the brake cooling ducts?

They are. They're an inexpensive no brainer.

Clean rotors, change fluid after ea track day and just get a separate set of pads just for track days. Hawk DTC-60 pads for front or some similar hi temp hi friction pad. Don’t use street pads at track you just end up melting them and smearing pad material on your rotors giving you an uneven braking surface.

I'm going to do that. Thanks for the input, I appreciate it
